Leucanthemum plant named ‘Real Glory’

ABSTRACT

A new cultivar of  Leucanthemum  plant named ‘Real Glory’ that is distinguishable by tight clumping habit, mid-dark green foliage and reflexed inflorescences with cream-white ray florets surrounding and contrasting with yellow disc florets, is disclosed.

Genus and species: Leucanthemum×superbum.

Variety denomination: ‘Real Glory’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Leucanthemum commonly known as Shasta daisy, which is grown as an ornamental plant for use in the garden and landscape. The new cultivar is known botanically as Leucanthemum×superbum and will be referred to hereinafter by the cultivar name ‘Real Glory’. This application is co-pending with the application for the inventor's variety of Leucanthemum plant named ‘Real Dream’ (U.S. application Ser. No. 13/986,665).

Leucanthemum is a genus within the family Asteraceae in which the commonly referred to “flower” is botanically the inflorescence which is comprised of outer showy ray florets surrounding smaller disc florets.

‘Real Glory’ arose and was selected from an ongoing breeding program which is conducted by the inventors at the inventors' nursery in West Sussex, United Kingdom. The breeding program commenced in 2006 with the aim of developing new and improved commercial varieties of Leucanthemum. Each year's breeding cycle consists of controlled pollination between chosen male and female parents including unnamed and unreleased seedlings retained from previous breeding cycles. Seed from each year's cycle is harvested and sown in the fall, and new seedlings are raised and evaluated in the following summer.

‘Real Glory’ is a seedling selection that resulted from the controlled pollination of a single plant of Leucanthemum ‘Fiona Coghill’ (unpatented) as the female parent, using pollen from a single plant of Leucanthemum ‘Leumayel’ (U.S. Plant Pat. No. 19,242) as the male parent. The inventors selected ‘Real Glory’ based on the criteria of vigor, reflexed ray florets and contrasting eye comprised of dense arrangement of yellow disc florets.

‘Real Glory’ was first asexually propagated by the inventors in West Sussex, United Kingdom in 2008 using the method of vegetative division and subsequently by basal shoot cuttings. Since that time under careful observation ‘Real Glory’ has been determined uniform, stable and true to type in subsequent generations of asexual propagation.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Real Glory’. In combination these traits set ‘Real Glory’ apart from all other existing varieties of Leucanthemum known to the inventor. ‘Real Glory’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

-   -   1. ‘Real Glory’ exhibits tight clumping habit.     -   2. The foliage of ‘Real Glory’ is mid-dark green in color.     -   3. The inflorescence of ‘Real Glory’ is 8.5 cm in diameter and         comprised of ray florets arranged around the central disc.     -   4. The ray florets of ‘Real Glory’ are cream-yellow in color.     -   5. The ray florets of ‘Real Glory’ develop initially in a flat         horizontal plane but rapidly become markedly reflexed.     -   6. The flowers of ‘Real Glory’ are carried on a strong stiff         stem and remain fresh in appearance for 10 to 14 days on the         plant.     -   7. Flowering of ‘Real Glory’ commences in early summer and         continues until fall.     -   8. After one year of growth in a 1 gallon container, a plant of         ‘Real Glory’ is 60.0 cm in height and 40.0 cm in width.     -   9. ‘Real Glory’ prefers a rich moist well-drained medium.     -   10. ‘Real Glory’ is hardy in USDA Zone 5 (−20° F. or −28° C.).

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

‘Real Glory’ is distinguishable from the female parent by the color of its ray florets and the prominence of the yellow eye. Whereas ‘Fiona Coghill’ exhibits cream-white ray florets, the ray florets of ‘Real Glory’ are cream-yellow in color. In addition, the inflorescence of ‘Real Glory’ is distinguished by a prominent yellow center comprised of yellow ray floret petal bases and yellow disc.

‘Real Glory’ is distinguishable from the male parent by inflorescence form. Whereas the inflorescence of ‘Real Glory’ consists of markedly reflexing ray florets, the ray florets of ‘Leumayel’ are arranged in a single layer.

The variety of Leucanthemum which the inventors consider to most closely resemble ‘Real Glory’ is the reflexed female parent variety ‘Fiona Coghill’. Whereas ‘Fiona Coghill’ exhibits cream-white ray florets, the ray florets of ‘Real Glory’ are cream-yellow in color. In addition, the inflorescence of ‘Real Glory’ is distinguished by a prominent yellow center comprised of yellow ray floret petal bases and yellow disc.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Leucanthemum cultivar named ‘Real Glory’ showing the color of foliage and flower as true as is reasonably possible to obtain in color reproductions of this type. Color in the photographs may differ from color values cited in the detailed botanical description, which accurately describe the actual color of ‘Real Glory’. Both photographs were made using conventional techniques and although flower and foliage color may appear different from actual color due to light reflectance, it is as accurate as possible by conventional photography.

FIG. 1 illustrates an eighteen-month-old plant (from initial cuttings) which has been grown in a frost-free greenhouse in Gensingen, Germany. This photograph illustrates the robust habit of ‘Real Glory’ with stems and flowers held stiffly-erect. The illustrated plant has not been pinched or treated with any chemical growth regulators.

FIG. 2 depicts a close-up view of the flower on a 12-month-old plant of ‘Real Glory’ which was growing outdoors at the inventors' nursery in West Sussex, United Kingdom.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new cultivar ‘Real Glory’. Observations, measurements, values and comparisons were collected in Santa Barbara, Calif. during summer, from a 12-month-old plant growing outdoors in the garden border. Color determinations are made in accordance with The 2007 Royal Horticultural Society Colour Chart from London, England, except where general color terms of ordinary dictionary significance are used.
